The trouble with weight sleds is the variability of the surface you are dragging it over. Wet clay will be a lot slicker then packed gravel etc. A fair test would be a tractor pulling on topsoil with about 5% moisture in it similar to what a field is when it is workable. The load should be coming up out of a well and over a well lubed bull wheel. Increase the load on the bottom of the cable until the tractor can't lift it off the bottom of the well. The last load it could lift would be its draw bar pull. Once started the tractor should be able to pull any load all the way to the top of the well if the ground is uniform.I believe that the best way to measure traction is likely to be some form of weight sled, similar to what is used in tractor pulls.
